HYDRoCAirBoN-BURNER.

SPECIFICATION forming part of Letters Patent No. 256,551, dated April 18, 1882.

Application led January 5, 1861. (No model.)

Burners, of which t-he following is afull, true,

and exact description, reference being had to Vthe accompanying drawing.

My invention relates to a method ot' automatically regulating the combustion orl heat produced by a hydrocarbon-burner under boilers or other similar places where pressure is generated; and it consists in combining, with the naphtha or naphtha and water supply pipes leading to such burner, a valve or valves controlled automatically by the pressure produced bythe combustion, and so arranged as to automatically control the supply of liquid fuel without completely cutting oft' the same. A preferable way to accomplish this result is by means of what is known as the LClark Damper,77 though equivalent methods might be resorted to.

Myinvention will be clearly understood from the drawing, which represents a view, partly perspective and partly broken, of my apparatus in situation under a boiler. B represents generally the boiler, and F the fire-box thereof. A naphtha burner, A, is therein located. This may be of any of the kinds well known; but I prefer to have one in which water and steam are burned together.

C represents the pipe for supplying water or steam, as the case may be, tothe naphthaburner, and D-the naphtha-supply pipe.

G represents one of the orifices ot' the naphtha-burner, which is used to heat the retort where decomposition occurs.

H represents a valve controlling the watersupply, and J a valve controlling the naphthasupply. Kis a connecting-rod movedvertically by the Clark damper L, which may be made adjust-able by sliding weight M. The stems controlling valves H. and J are controlled by adjustable nuts N N N N. The upward movement of the rod K may be limited 4by an adjustable stop, P,for a purpose to be explained.

rlhe operation of my apparatus will now be readily understood. In the ordinary condition, and before steam has been generated, the

shown in the drawing, and water and naphtha will be allowed to iiow into the burner A and be there'consnmed, thereby heating the boiler and making'st-eam. As soon, however, as the pressure in the boiler is sufficient to counterbalance the weight M Vthe rod K will begin to rise, thereby shutting off the water and naphtha supply. The .extent to which this supply is reduced can be determined by the adjustment of the stop P; because it would be undesirable to shut oft' the How altogether, and because so doing would necessitate kindlin'g the tire afresh. By having the positions of the valves relatively adjustable the apparatus may be so arranged that the water will be entirely shut off, leaving a limited supply of naphtha, which will burn at the point G and keep the apparatus hot and ready to start afresh when the steam falls in' theboiler B. y thismeans an exact regulation of the supply of' fuel to the boiler by means ot' the pressure existing in such boiler is obtained, while at the same time theapparatus mav be so adjusted as to maintain a constant tire under all circumstances.

I am aware that the draft leading to the tirebox in boilers has been controlled by a Clark damper connected with the boiler before my invention; and I do not claim broadly the idea of controlling the tire beneath a boiler by the pressure in a-boiler.

apparatus will be substantially'in the position I do not claim broadly a pressure-regulator combined with the heating devices ot" a generator, nor do I claim a pressure-regulator for regulating the ilow of gases and provided with adjusting appliances, both being old; but

VI do claim as my invention and desire to secure by Letters Patent- The combination of the burner A, steam or waterand naphtha pipes communicating therewith, a pressure-regulator, cocks in thepipes, and adjustable connections between the regulator and cocks, substantially as specified, whereby both the amounts and the relative supply of the naphtha and water are determined by the regulator, while the total stoppage ofthe fuel-s upply is prevented, as set forth,
